I have on my 360. It took a fair bit of time and strength to stall it, and I'm 225lbs in my birthday suit. But a lot of guys have never even thought to try it. It really is those of us that straddle the military and civilian jumping worlds that try it. But we are a minority
I'm not trying to build a team of MFF swoopers. However,when we jump with combat equipment and O2 at night on a unmarked, unlit, and unknown DZ but the spot was wrong, that the guys can pilot the s**t out of their canopy to a safe out.
